How Low Did it Go?
The extent of frost/freeze damage to a plant depends on a number of factors, including how cold it got, how long it remained at that temperature, and the microclimate of the field.
UNL State Climatologist Al Dutcher provides the following overnight (Sept. 11) reports from western Nebraska, where air temperatures were lowest.
Automated Surface Observation Systems (ASOS) reports at airports were:
- Chadron: Air temperature of 32°F for less than one hour
- Alliance: Air temperature of 33°F for 3 hours under cloudy skies
- Scottsbluff: Air temperature of 33°F for less than one hour
- Kimball: Air temperature of 32"F for 8 hours, 6 hours under clouds
